Given numbers are 688,870,284,494
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 688,870,284,494 is 5248473360.
Find LCM of 688,870,284,494 with Prime Factorization
2 | 688, 870, 284, 494 |
2 | 344, 435, 142, 247 |
172, 435, 71, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 172 x 435 x 71 x 247 = 5248473360
Therefore, the lowest common multiple of 688,870,284,494 is 5248473360.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
688 x 870 x 284 x 494 = 83975573760
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
284 : 1, 2, 4, 71, 142, 284
494 : 1, 2, 13, 19, 26, 38, 247, 494
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,870,284,494, is 2.
Now, the common factors can be found like this.
688:2x 2x 2x 2x 43
870:2x 3x 5x 29
284:2x 2x 71
494:2x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2 = 8
Therefore, the value for common factors is 8.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 83975573760/(2x8)
LCM = 83975573760/16
LCM = 5248473360
Thus, we can understand that the LCM of 688,870,284,494 is 5248473360.
